Abstract

Over 100,000 electric motors drive the production equipment throughout a large chemical company. The energy-efficiency and reliability of these motors during their entire life have a decided impact on the company's manufacturing costs and production capability. The Corporate Motor Technology Team (CMTT) conceived and led a program to optimize the cost effectiveness and reliability of new motors and developed criteria to determine whether to repair or replace motors that fail. The higher energy efficiency of the electric motors offered by vendors today plays a crucial role in these decisions. The company's current motor specification, procurement, maintenance, repair and replacement practices are vastly improved and consistent across the corporation. The 1995 savings attributed to the higher energy efficiency of over 2000 motors installed the prior year amount to $570,000 and will continue to accrue year after year. So will the savings stemming from lower maintenance cost and reduced downtime.
